ULN2805A General Description

The ULN2801A-ULN2805Aeach contain eight darlington transistors with common emitters and integral suppression diodes for inductive loads. Each darlington features a peak load current rating of 600mA (500mA continuous) and can withstand at least50V in the off state. Outputsmaybe paralleled for higher current capability.

Five versions are available to simplify interfacing to standard logic families : the ULN2801Ais designed for eneralpurpose applicationswith a current limit resistor ; theULN2802Ahas a 10.5kW inputresistor and zenerfor 14-25VPMOS; theULN2803Ahas a 2.7kW input resistor for 5V TTL and CMOS ; the ULN2804A has a 10.5kW input resistor for 6-15V CMOS and the ULN2805A is designed to sink a minimum of 350mA for standard and Schottky TTL
where higher output current is required.

All types are supplied in a 18-lead plastic DIP with a copperleadfromandfeaturethe convenientinputopposite- outputpinout to simplify board layout.
